David de Gea will join Manchester United after the European Under-21s ­Championship

Uruguay hitman Forlan, 32, who joined United at 22 and scored ten goals in 63 games over two seasons, said: “I am ­confident he will be a top player.”

It’s understood United have an ­£18million deal in place for Spanish Under-21s ­international keeper de Gea, 20, who will join after the European Under-21s ­Championship in ­Denmark is over as ­replacement for Edwin van der Sar.

Forlan said: “David will become a top player because he has a lot of ability.

“But he’s only just had his first full season as Atletico’s No.1 and he is a young guy with little experience.

“David is from a little town outside ­ Madrid and has been at Atletico since he was very young. He doesn’t speak any ­languages other than Spanish but he is ­going over with his girlfriend and family though, which will help.”

Uruguay forward Forlan left home at 19 and added: “You never know for sure ­whether a player will adapt to a new ­ country until he gets there.
